Abstract: 138,350. Hedman Manufacturing Co., (Assignees of Fesder, D. F.). March 2, 1916, [Convention date]. lndex type-wheel machines.-A machine for printing the amount on a cheque comprises a series of type-members for printing characters cf different denominations, and a type-bar for automatically printing an extra symbol, such as " Pay $," immediately at the left of the character of highest denomination, the presence of the extra symbol in the printed amount preventing the amount from being increased. In the machine shown in Figs. 2 and 3, the type-members are mounted in a casing 7, pivoted on a rod 8 on the base 9, and comprise type-disks 16 - - 22 for printing characters from 0 to 9 in different denominations, a sliding type-bar 35 for printing the extra symbol, a type-block 33<1> for printing the word " and " between the dollars and cents, and a type-block 32 for printing the contraction " cts " at the end of the amount. The typemembers are inked in the usual manner by a movable pad 50. The casing is depressed for impression by means of a lever 12, and is returned by a spring 10. The type-members co-operate during impression with a platen 24 on the base. The type-disks 16 - - 22 are mounted on a shaft 15 in .the casing, and are provided with setting. levers 29 which pass through slots 29<a> and are each provided with an index-plate 30, passing below an opening 31. The type-disks are formed with notches 26 for engaging spring-pressed detents 25. The type-disks are separated by spacing-members 51 which, in manufacture, are formed with a dished part 52 and are then placed between two members and pressed to the required thickness. Normally, the type-disks 16, 17, 18 are in position to print zero, and the type-disks 19 - - 22 are out of the printing line. The typeblocks 32, 33<1> are stationary with respect to the type-disks, the blocks being formed on carriers which pass over the shaft 15 and engage a rod 33. The type-bar 35 is mounted to slide on a carrier 36 which passes over the shaft 15 and engages the rod 33. The type-bar is connected to a spring 37, Fig. 3, which is pivoted at 38 on the carrier 36 and is connected to a bell-crank 39 which is pivoted on the casing and engages a slot 42 in a stationary arm 43. A set of stop-levers 19' - - 22<1>, pivoted on a rod 46<1> and pressed inwards by a spring comb 49, are normally retained by the engagement of lugs 48 on the stop-levers 19<1> - - 22' with the ends 45<1> of arcuate slots 45 in the typedishs 19 - - 22 respectively. When any of the type-disks 19 - - 22 are set, the associated stoplevers 19' - - 22' are released and move into the path of a stop 46 on the type-bar. On depressing the impression-lever 12, the type-bar is moved forward by the spring 37 until the stop 46 engages the first of the projected stop-levers, the type-bar being thereby arrested when it is almost in contact with the set type-disk of the highest denomination. The stop-levers pass between guides 47. Machines for perforating paper.-The typemembers and the platen are formed with interengaging ridges or corrugations.
